Abstract
L'invention concerne un procédé pour le revêtement d'une surface d'un élément métallique, en particulier un élément métallique d'un dispositif prothétique, comprenant les opérations consistant à : se procurer un bain électrolytique comprenant : au moins un collagène, des ions calcium et des ions phosphate ; immerger dans ledit bain électrolytique au moins une cathode et au moins une anode, ladite au moins une cathode comprenant l'élément métallique devant être revêtu ; appliquer un courant électrique continu audit bain électrolytique de façon à obtenir sur ladite surface un co-dépôt électrolytique de collagène avec un composé de phosphate de calcium comprenant de l'hydroxyapatite. La couche de revêtement ainsi obtenue a une biocompatibilité élevée, de façon à obtenir une interface entre un élément métallique et une structure osseuse, ce qui permet une formation osseuse nouvelle plus rapide et un renforcement de l'intégration osseuse au cours du temps.
